PATENT OFFICE:

THOMAS WILLIAM norm, or 'STALEYBRIDGE, ENGLAND.

YARN-CLEANING DEVICE.

H L'r, a subject of the King of Great Britam and Ireland, residing at 79\Villwood Terrace, \Vakefield Road, Stale'ybridge, in

the county of Chester, England, engineer, have invented new and usefulImprovements in Yarn-Cleaning Devices, of which the fol- 7 i .Theordinary or lowing is a specification.

This invention relates to improvements connectedwith or applicable totension imparting or clearing mechanism used on machines for dealing.with yarn, thread, and thelike.

In particular it wherein. is employed -one or'inore disks or clearingdevices .which is or are rotatable or movable relatively. I

best known type of ten sion or drag device at present employed in.-'cludes a suitable guide or guidesand a drag board covered withflannel'orsuch like, and

this has been extensively, used, and while '.considerable fly or waste:is produced by' directed tq that end.

this system. the method makes,piecing-up and threading a very simplematter.

.lVith the rotatable tension disks or de-' vices, while better yarn andless waste is produced, the employment of the rota-table tension devicesgives -more work to the attendaiit because it is necessary to pass theyarn or ends between the rotatable parts and the yarn must be accuratelyguided and Now, according to my invention, I provide, in combination.with, said tension devices, means which insure that the yarn isautomatically directed between the rotatable devices, that is, by themere pressing down of the yarn between co-acting guides, the same isdirected lIltO- position exactly ready for entrance between therotatable devices, with result, that, immediately the pull or tensioncomes on the yarn, the same necessarily passes intoposition and betweenthe rotatable devices which are to exercise the clearing and tensioningeffect.

The object in view can be carried out by various simple devices, as forexample, by using oppositely disposed inclined planes one front and theother back of the tension device, the planes deflecting the yarn andthrowing it in exact alinenient with the entrance level at, which themeeting faces Specification of Letters Patent.

I contact. Provision is also made whereby the yarn can slip below one'orboth of said inclined planes, with the idea, that, immediately tensioncomes on the yarn, the same s drawn into a more or less straight path.and so is properly disposed between the rotatable or other tensiondevices and con- .tinues to pass in proper fashion until the In theattached drawings I illustrate how my invention canbe carried intopractical effect, the said drawing showing a rotatable disk tensiondevice with directing contriv-i' ances which deflect and guide the yarnin most automatic threading can be effected.

Referring to the drawings; Figure 1 shows in side elevation my completeselfthreading tension device." Fig,,2is a plan view of Fig. 1. Fig. '3is a Section. Fig. 3 is a detail view. F ig. 4 shows a separate planview of the carrying base or castsiron such manner that exceedinglyrapid andalsupporting bracket. Fig. 5 is. detail view 0f the rear wire.Fig. (3 is a detail view of a modified form of'rear wire. The cast-ironbracket ais adapted tobe fixed to a railor support such as b and is heldby a pinching screw a or otherwise. To the bracket (in is attached aslotted steel guide plate 0 and said. bracket (1. has a forwardbifurcated pbrtion a The bracket has also a cast projection orupstanding portion a and is bored for the beai-ingpin e to which isfixed the lower disk hich preferably has a shallow central its upperface. Resting upon tl ie' lower disk f is the upper or loose dished disk9 which is adapted to receive weights or washers g. I. find that for thepurpose of iy invention, wire deflecting devices serve well and these Ipreferably apply to or carry from the cast-iron brackets. In thecase ofascending yarn, I use a wire device which has an upright limb h and isthen bent downward and forward, as at 71, to produce an inclineddirecting plane. The upright limb IL- is fixed in a hole a in thecast-iron bracket a, and held by a pinching screw if, or otherwise, and,the lower end of the inclined limb h is bent in, a little at h. Thisinclined limb does not reach down to th'ecastpression on iron bracket 0,but terminates about. the line limb which is. oppositely, disposed 'tothe other inclined limb of the first bent wire. In the drawing, I show acurved limb i (see more particularly Fig. 5). This limb may be bent orprovided witha loop or eye, below' whichthe yarn can pass to preventlifting of the upper-disk. I have not however found this necessary. Thewire of the limb o'r -loop i is bent and continued downward so that thecomplete guide .can be fixed by pushing the two ends into holes aa inthe cast-iron bracket as shown. I may produce both the yarndirectingplanes from one length of wire or in the form of a complete devicereadily attachable to the cast-iron bracket.

My invention includes directing inclines,

-- As thus-liberated from the influence of said inclines, &c., the pullor tension. of the yarn directs the end properly between the ,rotary orother tension or clearing-devices instantly and without requiring skill,the inclines, &c., themselves insuring automati'c deflection anddirection.

In the drawings, the yarn isshown as passing upward, then through thetension motion and over the bar or ledge a and around the postconstituted by the wire i to ,an ordinary drop wire j and then upwardagain, but the manner of directing the yarn would vary "e'ryconsiderably.

It will be understood, that my improvements are applicable to a varietyof tension.

or clearing devices having rotatable or disk like elements and the exactconstruction of the directing inclines, guides, or the'like wouldrequire modification according as one or'more ends are dealt with, andaccording; as to whether the yarn or the like passes up or down to thewinding on or like devices. When the yarnvwould pass upward, I- mightprovide the rear wire '1? with an overhanging' hook or curl'su'ch as i.see Fig. 6. I may dish ,or recessfthelddttom or under face of the lowerdisk f and I may cut a number of holes or slots in said lower disk f asshown at f in the detail Fig. 3 I declare that what I claim is.)

A yarn tension device having a bracket,

' a slotted steel guide attached thereto, a for ward bifurcatedextension on said bracket having a laterally extending lug, rotatableadjacent tension disksadeflecting guide adjustably securedin said lug inadvance of the tension disks and to one side thereof, said guidecomprising a wire-having a limb that extends upwardly then downward-andforward and then slightly curvedly inwardly to produce an inclineddirecting plane terminating in line with the contacting faces of. thedisks, a-ncl'a double curved defleeting guide inre ar ofsaid disks,said. guides adapted to throw' the yarn-tangeir;

In testimony whereof I have signed my name tothis specification -inthe'presence of two subscribing witnesses.
